Why Medicine Essay: How to Write It, With an Annotated Example

The first time Mr. Alvarez asked me to stay, I thought he wanted help with his tray. I was a volunteer on the evening shift of a cardiac step-down unit, and my job was water pitchers and warm blankets. He pointed at the discharge sheet on his table and said, quietly, that he could not read it. He had been nodding along all afternoon.

I read it to him slowly, twice. Then I found his nurse, who brought the resident back to explain the new medications in Spanish. I watched the resident sit down, draw his three pills on the back of the sheet and ask him to tell her, in his own words, when he would take each one. It took eight minutes. He went home the next morning with the drawing folded in his shirt pocket.

That evening did not make me want to be a doctor. It made me curious about what the resident was doing that I was not. Over the next two years I tried to find out. I shadowed a family physician at a community clinic for 120 hours, where most visits were about managing two or three chronic conditions at once. Her questions did two jobs: they gathered the history she needed, and they told the patient what mattered. When one patient's A1c had climbed, she did not start with the number. She asked him what his week looked like.

Not every visit ended well. One afternoon a patient left before she was seen because she had waited ninety minutes and had to get back to work. The physician called her that evening, moved her next visit to the first slot of the day and asked our front desk to flag anyone who might have to leave early. I had thought of medicine as what happens in the exam room. I started to see how much of it is whether a patient can get into the room at all, and that a physician can change that too.

I also worked for a year as a medical assistant, rooming patients, taking vitals and calling in refills, and I learned how much of care happens without a physician in the room. Nurses, pharmacists and our front desk staff caught problems I would have missed. That year made clear what I want my own role to be. I want to be the person who holds the whole picture, who decides with the patient when the plan has to change and who is responsible for that decision. The parts of medicine I keep coming back to are diagnosis under uncertainty and the conversation that follows it.

Research taught me the first of those. In a pharmacology lab I spent a semester on an assay that kept failing, and for weeks I changed three things at once and learned nothing. My mentor made me slow down. I learned to change one variable at a time and to write down what I expected before I looked at the result. That habit has followed me into the clinic, where I now catch myself forming a guess before a patient finishes the story, and holding it loosely.

The third test was the one I expected least. For eighteen months I volunteered with a hospice program, sitting with patients so their families could rest. There was nothing to fix. Most visits were quiet: reading the newspaper aloud, adjusting a pillow, calling the nurse when a patient's breathing changed. One patient, a retired machinist, asked me every week to explain what his doctors had told him, and I learned how often I did not know. I started writing my questions down for the hospice physician, and she answered every one. She told me the hardest skill in medicine was telling someone the truth in a way they could still carry. That sentence has stayed with me longer than anything I learned in a lab.

I have also seen what the work costs. The family physician I shadowed finished her notes at nine most nights, and on the hardest day I watched her deliver a cancer diagnosis and then walk into the next room smiling for a toddler's checkup. I asked her later how she did it. She said she did not always do it well, but that she had decided the next patient deserved her full attention too. I do not think I understand that fully yet. I do know it is the kind of physician I want to become, and that I am willing to do the long training it takes.

I still think about Mr. Alvarez's shirt pocket. The drawing was not advanced medicine. It was a physician deciding that understanding was part of the treatment. The hospice physician said the same thing in different words. Medicine will ask me to keep learning for decades and to sit with people on their worst days, and I want to spend my career doing both halves of that work: getting the medicine right, and making sure the person who has to live with it can carry it home.
